To all whom it may concern: Y

Be .1t known that I, KENNETH N. HEALY, a citizen of the United-States,residing kat River Falls, in thelcounty of Pierce and` State ofWisconsin, have invented certainl new and useful Improvements ink a:Door

Construction for HogHouses, of which the following is a specification. f

Thisinvention relates to a new and useful improvement in doorconstruction for hog houses, and has for its principal object to providesimple and efiicient means for opening and closing the door.

Aiifurtherobject of the invention is to provide a door which visadaptedfor vertical sliding movement in opening or closing thedooropening, guide means'being provided for permitting the proper slidingmovement of the door;` p

Alfurther object `of the! Ainvention is" to provide a doorconstructionffor hog houses Oflthe aboveinentioned character, which ,is

simple in construction, inexpensive, strong A the arrangement of the'guide members and the guide means carried by the door.

Figure 3 is a transverse section, throughthe door, showing the manner,in which the a guide rollers co-operate with the guide rails, and f Yproximately on the line JC- 4l 4of Figure 2; l v

Figure a is al sectional view, taken ap- In the drawing, wherein for thepurpose of illustration is shown the preferred embodiment of myinvention, the numeral. 1

l designates a portion of a hog house, and

the same includes the floor 2, the door open- Y ing 3, .provided in theside 4, and the rafter 5.

The door posts, which arel provided on the inside of the sidewwallfi,adjacent the respective side edgesof t-he door opening 3 `aredesignatedby the numerals 6 and 7 respectively.

Extending upwardly from the floor 2, on

each side of the `door opening and beingf spaced from the door posts 6and 7 -are the tubular guide` rails 8 and@ 9 respectively. The lower`ends of the guide rails may be embedded in theconcrete floor 2, or maybe` `otherwise supported in a Vsecure position,

and-"Ido not wish to limit myself to any particular manner' in which thelower ends of the guide rails are fastened. The upper portions of thetubular guide rails, at points above t-he upper edge ofthe door opening3, are vinclined upwardly as illustrated at 10 and 11 respectively, inthe drawings, and the upper ends of the inclined portions are disposedinwardly and are fastened to the rafters 5, by any suitable fasteningmeans, in the manner as illustrated, more clearly at 12 in the drawings.It is also apparent that the 'upwardly inclined (portions 10` and 11 arespaced from therafters', so as to permit the freel ,'.slidingf movementof the door 13;

For the purpose'of bracing the intermediyate portionsof the tubularguiderails, I provide thebracing means, the construction of which ismore clearly illustrated -inFigure 4.

of the drawing, and the same comprises substantially U-shapedmembers 14,one'arm of each member l14` being of greater length than the other arm,vand the longer arm being fastened at its outer end to one door post, inthe manner as illustrated at 15. The

,shorter arm 16 of each of thek U-shaped bracing members has `its outerend seatable in l .a suitable opening provided in each ofthe guiderails,and if desired, a threaded connection maybe provided between the,shorter arms of the U-shaped bracing members and the tubular guiderails. The U-shaped bracing members are preferablyv arranged at thejunction of the vertical portions of the tubullar guide rails, and theinclined portions thereof, inthe manner as clearly illustrated in Figure1 of the drawings. a Y

The door 13 may be ofV any suitable construction, and the same isadapted for vertical slidable movement between the door posts 6 and 7respectively. Extending transversely across the upper portion of thedoor, on the inside thereof, is the shaft 17 and the same is journalledin suitable brackets 18, which entend from the side edges of the door,in the manner as clearly illustrated in Figure 3. A

The ends of the shafts 17 extend beyond the sides of the door and carrythereon the rollers 1S) and 2O respectively, the same being adapted' forengagement with the guide rails 8 and 9, and also the inclined portions10 and ll of the guide rails. Ext-ending across the bottom of thel door,on` the inside thereof, and fastened thereto in any suitable manner isthe guide rod 21, and the ends thereof extend beyond thesidesof. thedoor, and are bent rearwardly, as illustrated at for engagement withlthe tubular guide rails 8and9. V- f.

For the purpose of operating the door, so that thesaine `may be moved'toeither an. open or closed position, I provide the actuating cable 22,one end of which is fastenedV to the upperA edge of the door, asillustrated at 23, and the cable is adapted to extend aroundoa vsuitablepulley 24, supported by the ratter 5', in the manner as clearlyillustrated in Figure l. Y

As shown. in Figure 1 of the drawings, the door 13- is in a closedposition and covers the door opening 3.l vWhen it isA desired to openthe door, softhat the hogs may pass through the door opening, the freeend of thevcable 22 is actuated, and the door will be caused to moveupwardly between the door posts, andas theV door is `raised, the guiderollers 19v and 20, on thel upper portion of the door will cooperatewith thetubular guide rails, which are inclined at their upper portions,while the guideprod 21 on the lower end ofV the door will have its treeends engaging the vertical portions 8 and 9 ot the tubular` guide rails,so that the door will be supported inl proper position, when the same isoperated. lVhen the door. has been raised to uncover the door openinmand., thev door-is in the position as shown in the dotted lines inFigure l of the drawing, the free end of the cable may be fastened tosupport the door in such position, at which v timethe ends of the rod 2lwillengage the U-sha-ped members 14 so as to limit the upward movementof the door.

The provision of a door construction of thel above mentioned character,for hog houses will enable the latter to be constructed at a very lowcost, and will further obviate the necessity of having to provide sidewalls ot great heigli f such as is now done, and by constructing a hoghouse wherein the Vside walls are relatively low, the house may be keptwarinin the winter weather and a more even temperaturemay be had, duringthe warm weather. The simplicity of my device enables the sameto beeasily and etticiently operated, and will further be streng and durable,as well as inexpensive.

'Vhile I have shown thepreferred embodiment of my invention, it is to beunderstood that various changes in the size, shape, and arrangement otparts may be resorted to, without departing tromV the spirit of theinvention,y and the scope of the appended claim.A

Having thus described my invention, what I claim is:

In combination with a building structure provided at its side wall witha door'opening and having a roof disposed in an inclined position abovethe door opening, a door structure including guide railseXtendingvertically along the sidewall of the building'and beingdisposed parallel with the side wall fromA points belovvthe lower edgeof the door opening to pointsabove the upper edge thereof, the yupperportion of the guide rails being extended Vunder the roof andapproximately parallel with the same, `bracing members for the guiderails adjacent the juncture of the upper portions thereof with the lowerportions, .a door panel having at its lower edge guides which engage therails, rollers vjournaled von the upper edge of the door panel forengaging the rails, and means for raising the door to an open positionat which time the guides engage the bracing members.

In testimony'whereof I aiiix my signature.
